he's got a lot to work with. >> erick, if you watched the debate last night and watched this fascinating week, we've seen newt gingrich now catching up to mitt romney, even passing him in some national polls. ahead in a new iowa poll. if you're mitt romney, looking around the stage last night, you have to be hoping that you don't end up in a two-way or three-way. you want perry, you want bachmann, herman cain, rick santorum. you want them to survive iowa and have a crowded field moving on, don't you? >> you do. in fact, mitt romney's campaign has thrown several lifelines to candidates. in one of the debates, the bloomberg debate, he asked a softball to michele bachmann on what great things she would do for america. he has said nice things about herman cain and defended cain from attacks. he's trying to keep people in. there's a real problem, though, just from the cnn poll and other polls are starting to show this, as newt gingrich has now gone up beyond mitt romney, we're seeing something we haven't seen with other candidates. mitt romney is starting to go back down. he has been very, very steady in the polling with other candidates, bouncing around him.
